That is the classic symptom of a disconnected vacuum line. Check the vacuum lines where they come together at the back of the intake manifold.... I believe there is a 3-way junction. This is a common problem, especially for f-bods that have had the intake manifold off for one reason or another. (modded)

You may also want to replace the diaphram/valve that controls the vents. I have had to replac3e mine a couple of times and I know I'm not the only one.
